ISPconfig 3.0.5.1 - MySQL Remote IP / Any

since 3.0.5.1 it seems no more possible to activate the "Remote Access" for a database and allow "any" IP to connect to it. if i leave the "Remote Access IPs (separate by , and leave blank for any)" field blank and save the settings and then go back, the default IP address is entered, instead of having a blank field and the desired "any" access. can somebody confirm this bug?

UPDATE: if i add the IP address manually, the "default IP" is always added to that list. so that explains why an empty field doesn't result in "any" :-(
